To configure last participant support (LPS) for an application server, you set the ACCEPT_HEURISTIC_HAZARD custom property for the transaction service for that server. In this way, all applications that run on that server are enabled for LPS.
Last participant support is an extension to the transaction service that enables a single one-phase resource to participate in a two-phase transaction with one or more two-phase resources.
You configure LPS for an application server to specify that all applications on this server accept the possibility of a heuristic hazard occurring in a two-phase transaction that contains a one-phase resource.
If you do not set this property, or you set this property to FALSE, LPS behavior depends on the LPS setting of the application. You must configure applications individually to accept the heuristic hazard.
You can configure applications individually when they are assembled.
To configure LPS for an application server using the administrative console, use the following steps.
